Abstract
LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA PRODUCCION DE CUERPO MOLDEADO POROSO ATRAVESABLE POR CORRIENTE EN CARBURO DE SILICIO CON PEQUEÑAS RESISTENCIAS ELECTRICAS ASI COMO UN ELEMENTO DE FIELTRO DEL HORNO DE COMBUSTION PRODUCIDO SEGUN EL PROCEDIMIENTO. UNA MEZCLA EN POLVO GRANULADA APROPIADA POR EJEMPLO CONSISTENTE EN UN CONFORMADOR ORGANICO COQUIZABLE, SILICIO Y UN COMPUESTO NITROGENADO, SE FORMA EN CUERPO VERDE, SE COQUIZA EN UNA ATMOSFERA DE GAS INERTE O EN VACIO A UNA TEMPERATURA DE 600 A 1000 C Y A CONTINUACION SE SILIZA ENTRE 1400 A 2000 C. NO CONTIENE EL POLVO DE MEZCLA NINGUN COMPUESTO DE NITROGENO, SE REALIZA LA SILICICIACION EN UNA ATMOSFERA CONTENIENDO NITROGENO. VENTAJOSAMENTE LA CONFIGURACION DE LA INVENCION TRATA DE UN DETALLE INDIVIDUAL EN LA PRODUCCION DEL POLVO DE MEZCLA. CON AYUDA DEL PROCEDIMIENTO ES PRODUCIBLE UN ELEMENTO DE FILTRO DE HUMOS DE COMBUSTION DE DIESEL REGENERABLE Y CALENTABLE ELECTRICAMENTE.
